Photo Gallery: "Bodies" Cadaver Exhibition

A thin slice taken from a male cadaver's chest area shows the heart at center, with the cigarette-darkened lungs on either side of it. The white "dots" at far left and right show where upper-arm bones would be.

Like all the body parts in the "Bodies" exhibition, this slice is from an unidentified or unclaimed Chinese corpse.

Some critics oppose using such bodies, because the individuals or their families have not been able to consent to a public display. But, said Roy Glover, the chief medical advisor and spokesperson for the exhibition, "It is standard legal practice in both the United States and China that unclaimed or unidentified remains are made available for medical education, which is one of the key goals of our exhibition."
